One of the most difficult and intimidating tasks for any trader or investor is to try and determine when a particular stock has bottomed or reaches a point where it no longer decreases significantly. Everyone wants to buy low and sell high, but if you consider that a stock's price can be influenced by macroeconomic, political and economic events, stating with any certainty that a given stock has bottomed is a daunting task.

Also, your stock is just one of the thousands of stocks that trade daily in markets worldwide. Knowing when a stock has bottomed can unlock huge profits and can also prevent big losses. So how can one know with some confidence that a stock has reached a low point? No one can call stock bottoms with absolute certainty consistently, but there are some common fundamental and technical trends that appear in stocks that are about to hit bottom.

Key Takeaways While there is no way to know for sure when a stock has bottomed, there are a number of indications that a savvy investor can keep in mind.

Keeping an eye on the sector your target stock is part of and noting how it performs relative to the broader market can help you discern a bottom.

Price and volume are important indicators that a stock is at a key inflection point, especially if volume starts to pick up steadily.

Consider going against whatever the general masses think: if everyone is gung-ho about a particular stock, it might be time to sell.

Sector Characteristics

The stocks you own in your portfolios belong to sectors. Sectors are simply groups of public companies and stocks in a related industry. Oil and gas, technology, financial, and retail are some sectors that may be familiar to investors.

Typically, stocks follow in lockstep to both the overall stock market and their respective sector. Identifying which sector(s) your stocks belong to is a good first step in determining if your stock is near the bottom or a point of less intense declines.

Most of us are familiar with the credit market meltdown in 2008, which decimated financial stocks and even drove financial icons out of business. Most financial stocks traded downward together for an extended period of time. Investors who looked to find "value" in certain financial stocks were crushed, as the entire financial sector experienced a historical decline. The lesson learned is to identify and understand what sector your stock belongs to and compare its performance against the entire market.

Price and Volume

Once you identify your stock's sector, some other clues can give you some confidence your stock is nearing a bottom. Many technicians think stock price and volume are the two most important indications of where a stock is going. Stocks tend to bottom when there are few sellers of that particular stock.

It sounds ridiculously simple, but think about it: if few sellers exist, more buyers remain and buyers are more willing to pay a higher price for the stock. This means a price bottom has formed.

Volume adds credibility to stock prices and price direction, to an extent. Remember, stocks trade on supply and demand, just like all other goods in a free market. There are just a lot more things that influence stock prices than a gallon of milk. The higher the relative volume once the stock has finished going down, the more likely the stock will not see lower prices anytime soon.

So, if stock XYZ's average daily trading volume was 5 million shares a day as it declined 50%, but during the last three trading days it has averaged over 15 million shares daily and the price of the stock has appreciated, it is likely the stock has reached an inflection point and is done going down significantly. Remember, fewer sellers exist at lower prices as most people were looking to "sell high." If only buyers remain, stock prices will rise.

There are technical trading programs that will show you ideal times to buy and sell a particular stock, based on trading patterns, but they can't definitively show if a bottom has been made.

Keep Your Ear to the Street

Perhaps an overlooked tell of when a stock is bottoming is its perception by the general masses. Unfortunately, many average investors hear sound bytes on the business news and take it as gospel.

Ironically, there is an entire school of investment in which the main strategy is to go against conventional wisdom. These investors are aptly called contrarians. Contrarians tend to bet against what the "smart" money is doing. Many times going against the grain can be highly profitable and can also be helpful in determining if your stock has bottomed.

The oil and gas sector went through a significant bear market in sympathy with the great recession that began in 2007. Oil prices went down over 50% and stocks in the oil and gas groups were hemorrhaging.﻿﻿ Business news hyped up the decline and pundits were talking about the demise of oil and the use of natural gas substitutes and solar energy. No one wanted to touch an oil stock. Investors who went against the grain and snapped up blue-chip oil stocks saw a handsome profit. It pays to see all sides of a stock story.

Going against the grain is a strategy that many believe works well particularly at market tops and bottoms. As an investor, it is at least worth your time to listen to what everyone is saying and wonder: Can they all really be right?

The Bottom Line

Ideally, investors want to know when price trends are about to make a major change in either direction, whether they're reaching tops or bottoms. The bottom line is no one truly knows with certainty.

Clues, such as a big volume spike on price changes and paying attention to your stock's sector, will give you some insight into whether your stock has reached a point where it will no longer decline significantly.

Keep in mind that these are just pieces in the puzzle of investing, but if you can add this skill set to your investment knowledge, you will likely be a more successful investor.
