The Fed's decision to maintain a patient posture was not a foregone conclusion. In fact, I was becoming skeptical that the Fed would stand pat following significant pressure from the White House as well as recent comments coming from the Fed itself. ( See my op-ed on CNBC.com .) At least for now, the impulse to act was avoided. Yet judging by the markets' reaction, Powell & company appear to have set the expectation of rate cuts in the not-too-distant future. Are investors right to be so optimistic about the Fed's next move?

Federal Reserve Chairman Jerome Powell's performance last week received high marks. Not only did he re-establish Fed independence by not caving to White House pressure, but he was also able to craft a statement, deliver prepared remarks and answer questions without spooking the stock market.

While the Fed may have managed to avoid major landmines this meeting, I remain concerned about the market perception that major interest-rate cuts will be forthcoming. I am not so sure that this scenario will ultimately come to pass. The reality is that over two-thirds of the economy is doing quite respectably. Unemployment is at 3.6% and wage growth, while falling a bit in recent months, is still better than 3% and well above inflation.

Consumers, especially lower-income consumers, are finally starting to earn more and more fully participate in the economic expansion. And the strength in the stock market to all-time highs, while mostly benefiting the well-to-do, should support continued improvements in consumer confidence and spending. Is now the time to be reverting back to maximum monetary support?

Earlier this month, President Trump reiterated his contention that the stock market (he is using the Dow Jones Industrial Average, or DJIA) would be 10,000 points higher if Powell were not the chairman of the Federal Reserve. The implication was that had the president appointed someone willing to implement the president's desire for sharply lower interest rates, investors would have celebrated by bidding stocks up to major new highs.

Is he right? My answer is that it's not entirely implausible. At the time of the president's remarks, the DJIA was at about 26,100. A 10,000 point move in the DJIA would translate to about a 38% increase from that level. For simplicity, let's use the benchmark index that that most professional investors use - the S&P 500. A 10,000 point increase in the DJIA from last week's levels would translate into an S&P 500 level of about 4,000. Based on the expectation for S&P 500 earnings of about $176 over the coming year, this would take the price-to-earnings multiple for the S&P 500 from the current level of 16.7x to about 22.7x. In the chart below, you can see that a 22.7x multiple is also well above the long-term average of 15.7x, well outside of the standard deviation over the past 20 years (a range of 12.8x-18.7x, depicted by the gray bar), and well above anything we've seen since the Dotcom bubble. But is this level out of the realm of possibility? The answer is no.

An S&P 500 at 4,000 would clearly serve the president's agenda (read: reelection), but at what cost? The problem is that artificially pumping up the stock market to these lofty heights without a corresponding increase in earnings would pose a significant risk to the economy. We all know what happened the last time stock prices were that high. The market collapsed and the economy fell into a recession.

Then there is the question of how effectively interest-rate cuts would be in addressing the economy's current weaknesses. I noted earlier that consumer spending, representing over two-thirds of the US economy, is growing at a respectable pace (despite some first-quarter weakness). If this remains the case, which seems quite possible given the strong labor market, then the question becomes, are unreasonably high interest rates to blame for the current drags on economic growth? In particular, weak business investment has been the chronic source of disappointment. Is that likely to change if interest rates are, say, 1% lower? The answer is obviously no. US businesses just got a massive tax cut and used the spoils not to increase investment but rather to buy back stock. And trade-related uncertainty is undoubtedly a part of the problem as business leaders do not want to make investments before knowing the rules. But lower interest rates are not the answer!

In sum, the Fed is doing its job, and it must maintain its independence from political influence. Aggressively cutting interest rates will only juice asset prices, encourage more debt, pull forward more demand, and exacerbate the huge problem of economic inequality – all of which are detrimental to the economy's long-term growth outlook. So as long as economic conditions don't deteriorate meaningfully, it's a great time for the Fed to reassert its independence and reduce the economy's and stock market's heavy dependence on artificially low interest rates. For now, though, while the market's return to dependence on the Fed concerns me greatly, I must admit that the path of least resistance for stocks is likely higher.
