NEW YORK (Stockpickr) -- At Stockpickr, we track the top holdings of a variety of high-profile investors, such as Warren Buffett and Carl Icahn.

One of our most popular professional portfolios is that of David Einhorn's Greenlight Capital. As we look forward to 2015, we thought we'd single out some of Greenlight's recent top buys.

What follows is a closer look at 10 stocks that Einhorn bought in the most recently reported quarter ended Sept. 30. Each of these stocks comprises at least 1% of the Greenlight Capital portfolio and saw a position increase of at least 30%. Many of them were brand new purchases for the fund. They are ordered here by increasing position size.

10. Nokia (NOK) - Get Report comprises 1% of Greenlight Capital's portfolio as of the most recently reported quarter. The 7.8 million-share position was a new buy in the quarter.

TheStreet Ratings team rates Nokia as a buy with a ratings score of B-. TheStreet Ratings team has this to say about its recommendation:

"We rate Nokia (NOK) a buy. This is driven by multiple strengths, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its impressive record of earnings per share growth, compelling growth in net income, good cash flow from operations, expanding profit margins and largely solid financial position with reasonable debt levels by most measures. Although the company may harbor some minor weaknesses, we feel they are unlikely to have a significant impact on results."

Highlights from the analysis by TheStreet Ratings Team goes as follows:

Nokia reported significant earnings per share improvement in the most recent quarter compared to the same quarter a year ago. The company has demonstrated a pattern of positive earnings per share growth over the past two years. We feel that this trend should continue. During the past fiscal year, Nokia turned its bottom line around by earning $0.06 versus -$1.11 in the prior year. This year, the market expects an improvement in earnings ($0.35 versus $0.06).

The net income growth from the same quarter one year ago has significantly exceeded that of the S&P 500 and the Communications Equipment industry. The net income increased by 569.1% when compared to the same quarter one year prior, rising from -$149.37 million to $700.76 million.

Net operating cash flow has significantly increased by 3320.28% to $434.62 million when compared to the same quarter last year. In addition, Nokia has also vastly surpassed the industry average cash flow growth rate of -32.12%.

46.97% is the gross profit margin for NOKIA CORP which we consider to be strong. Regardless of NOK's high profit margin, it has managed to decrease from the same period last year. Despite the mixed results of the gross profit margin, the net profit margin of 19.23% trails the industry average.

NOK, with its decline in revenue, underperformed when compared the industry average of 5.6%. Since the same quarter one year prior, revenues fell by 17.6%. The declining revenue has not hurt the company's bottom line, with increasing earnings per share.

9. NorthStar Asset Magnagement Group (NSAM) comprises 1.2% of Greenlight Capital's portfolio as of the most recently reported quarter. The 4.5 million-share position was a new buy in the quarter.

TheStreet Ratings team does not currently maintain full coverage of NSAM.

8. BP (BP) - Get Report comprises 1.3% of Greenlight Capital's portfolio as of the most recently reported quarter. The 2.1-share position is an increase of 583.139 shares, or 39.4%, over the previous quarter.

TheStreet Ratings team rates BP as a hold with a ratings score of C+. TheStreet Ratings team has this to say about its recommendation:

"We rate BP (BP) a hold. The primary factors that have impacted our rating are mixed ? some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks. The company's strengths can be seen in multiple areas, such as its reasonable valuation levels, good cash flow from operations and largely solid financial position with reasonable debt levels by most measures. However, as a counter to these strengths, we also find weaknesses including deteriorating net income, disappointing return on equity and poor profit margins."

Highlights from the analysis by TheStreet Ratings Team goes as follows:

Net operating cash flow has increased to $9,399.00 million or 48.43% when compared to the same quarter last year. In addition, BP has also vastly surpassed the industry average cash flow growth rate of -1.58%.

The current debt-to-equity ratio, 0.43, is low and is below the industry average, implying that there has been successful management of debt levels. Although the company had a strong debt-to-equity ratio, its quick ratio of 0.98 is somewhat weak and could be cause for future problems.

Return on equity has greatly decreased when compared to its ROE from the same quarter one year prior. This is a signal of major weakness within the corporation. In comparison to the other companies in the Oil, Gas & Consumable Fuels industry and the overall market, BP's return on equity is significantly below that of the industry average and is below that of the S&P 500.

The gross profit margin for BP PLC is currently extremely low, coming in at 11.86%. It has decreased from the same quarter the previous year. Along with this, the net profit margin of 1.37% trails that of the industry average.

7. Chemtura (CHMT) comprises 1.3% of Greenlight Capital's portfolio as of the most recently reported quarter. The 3.95 million-share position is an increase of 1 million shares, or 35.1%, over the previous quarter.

TheStreet Ratings team rates Chemtura as a Hold with a ratings score of C+. TheStreet Ratings team has this to say about its recommendation:

"We rate Chemtura (CHMT) a hold. The primary factors that have impacted our rating are mixed ? some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks. The company's strengths can be seen in multiple areas, such as its compelling growth in net income, reasonable valuation levels and impressive record of earnings per share growth. However, as a counter to these strengths, we also find weaknesses including a generally disappointing performance in the stock itself, weak operating cash flow and poor profit margins."

Highlights from the analysis by TheStreet Ratings Team goes as follows:

The net income growth from the same quarter one year ago has significantly exceeded that of the S&P 500 and the Chemicals industry. The net income increased by 137.5% when compared to the same quarter one year prior, rising from -$40.00 million to $15.00 million.

Chemtura reported significant earnings per share improvement in the most recent quarter compared to the same quarter a year ago. This company has reported somewhat volatile earnings recently. But, we feel it is poised for EPS growth in the coming year. During the past fiscal year, Chemtura swung to a loss, reporting -$0.23 versus $1.03 in the prior year. This year, the market expects an improvement in earnings ($0.77 versus -$0.23).

Net operating cash flow has significantly decreased to $9.00 million or 93.38% when compared to the same quarter last year. In addition, when comparing to the industry average, the firm's growth rate is much lower.

CHMT has underperformed the S&P 500 Index, declining 13.04% from its price level of one year ago. Looking ahead, other than the push or pull of the broad market, we do not see anything in the company's numbers that may help reverse the decline experienced over the past 12 months. Despite the past decline, the stock is still selling for more than most others in its industry.

6. Time (TIME) comprises 1.5% of Greenlight Capital's portfolio as of the most recently reported quarter. The 4.4 million-share position is an increase of 1.1 million shares, or 31.8%, over the previous quarter.

TheStreet Ratings team does not currently maintain full coverage of TIME.

5. Aecom Technology (ACM) - Get Report comprises 1.5% of Greenlight Capital's portfolio as of the most recently reported quarter. The 3 million-share position was a new buy in the quarter.

TheStreet Ratings team rates Aecom Technology as a hold with a ratings score of C+. TheStreet Ratings team has this to say about its recommendation:

"We rate Aecom Technology (ACM) a hold. The primary factors that have impacted our rating are mixed ? some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks. The company's strengths can be seen in multiple areas, such as its revenue growth, attractive valuation levels and good cash flow from operations. However, as a counter to these strengths, we also find weaknesses including disappointing return on equity, poor profit margins and deteriorating net income."

Highlights from the analysis by TheStreet Ratings Team goes as follows:

The revenue growth greatly exceeded the industry average of 9.4%. Since the same quarter one year prior, revenues rose by 23.3%. This growth in revenue does not appear to have trickled down to the company's bottom line, displayed by a decline in earnings per share.

Compared to where it was 12 months ago, the stock is up, but it has so far lagged the appreciation in the S&P 500. Despite the fact that it has already risen in the past year, there is currently no conclusive evidence that warrants the purchase or sale of this stock.

The gross profit margin for Aecom Technology is currently extremely low, coming in at 6.01%. It has decreased from the same quarter the previous year. Regardless of the weak results of the gross profit margin, the net profit margin of 2.49% is above that of the industry average.

The company's current return on equity has slightly decreased from the same quarter one year prior. This implies a minor weakness in the organization. When compared to other companies in the Construction & Engineering industry and the overall market, Aecom Technology's return on equity is below that of both the industry average and the S&P 500.

4. ON Semiconductor (ONNN) comprises 1.9% of Greenlight Capital's portfolio as of the most recently reported quarter. The 15 million-share position was a new buy in the quarter.

TheStreet Ratings team rates ON Semiconductor as a buy with a ratings score of B. TheStreet Ratings team has this to say about its recommendation:

"We rate ON Semiconductor (ONNN) a buy. This is driven by some important positives, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its solid stock price performance, revenue growth, reasonable valuation levels, good cash flow from operations and expanding profit margins. We feel these strengths outweigh the fact that the company has had sub par growth in net income."

Highlights from the analysis by TheStreet Ratings Team goes as follows:

Compared to its closing price of one year ago, ONNN's share price has jumped by 29.54%, exceeding the performance of the broader market during that same time frame. Regarding the stock's future course, although almost any stock can fall in a broad market decline, ONNN should continue to move higher despite the fact that it has already enjoyed a very nice gain in the past year.

Despite its growing revenue, the company underperformed as compared with the industry average of 18.6%. Since the same quarter one year prior, revenues rose by 16.5%. This growth in revenue does not appear to have trickled down to the company's bottom line, displayed by a decline in earnings per share.

Net operating cash flow has significantly increased by 54.09% to $92.30 million when compared to the same quarter last year. The firm also exceeded the industry average cash flow growth rate of 11.94%.

41.76% is the gross profit margin for ON Semiconductor which we consider to be strong. It has increased from the same quarter the previous year. Despite the strong results of the gross profit margin, ONNN's net profit margin of 4.99% significantly trails the industry average.

3. Consol Energy (CNX) - Get Report comprises 2.7% of Greenlight Capital's portfolio as of the most recently reported quarter. The 4.9 million-share position was a new buy in the quarter.

TheStreet Ratings team rates Consol Energy as a hold with a ratings score of C+. TheStreet Ratings team has this to say about its recommendation:

"We rate Consol Energy (CNX) a hold. The primary factors that have impacted our rating are mixed ? some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks. The company's strengths can be seen in multiple areas, such as its revenue growth, compelling growth in net income and good cash flow from operations. However, as a counter to these strengths, we also find weaknesses including a generally disappointing performance in the stock itself and poor profit margins."

Highlights from the analysis by TheStreet Ratings Team goes as follows:

The revenue growth came in higher than the industry average of 6.3%. Since the same quarter one year prior, revenues slightly increased by 9.7%. Growth in the company's revenue appears to have helped boost the earnings per share.

The net income growth from the same quarter one year ago has significantly exceeded that of the S&P 500 and the Oil, Gas & Consumable Fuels industry. The net income increased by 97.4% when compared to the same quarter one year prior, rising from -$63.65 million to -$1.65 million.

Consol Energy reported significant earnings per share improvement in the most recent quarter compared to the same quarter a year ago. This company has reported somewhat volatile earnings recently. But, we feel it is poised for EPS growth in the coming year. During the past fiscal year, Consol Energy reported lower earnings of $0.35 versus $1.69 in the prior year. This year, the market expects an improvement in earnings ($0.89 versus $0.35).

The gross profit margin for Consol Energy is rather low; currently it is at 21.34%. Regardless of CNX's low profit margin, it has managed to increase from the same period last year. Despite the mixed results of the gross profit margin, the net profit margin of -0.19% trails the industry average.

In its most recent trading session, CNX has closed at a price level that was not very different from its closing price of one year earlier. This is probably due to its weak earnings growth as well as other mixed factors. Turning toward the future, the fact that the stock has come down in price over the past year should not necessarily be interpreted as a negative; it could be one of the factors that may help make the stock attractive down the road. Right now, however, we believe that it is too soon to buy.
