One of the most important realizations I've had recently is the investing motto: "You can't beat the market, but you can beat the tax man".<p>Don't try to be smart about your investments from the point of view of share pricing, P/E ratios, EBITDA, etc, etc. The legions of Harvard and MIT quants working on Wall Street are going to be better than you at figuring out what the stock price should be.<p>Instead, get smart about how the tax code works. Figure out the difference between long-term and short-term capital gains. Figure out how to do tax loss harvesting. Figure out what a back-door IRA is. Figure out how to take out a loan on your 401(k). The benefits from those investigations are going to be much more reliably beneficial than trying to be smart about pricing and timing the market.
