I strongly suggest that you do not confuse being an Investors with being a Trader. I’ve been pointing out for many years that the Stock Market is greatly influenced by day-traders, flash-traders, program-trading firms, in for quick trades of a few hours, a couple of days at most, and back out again. That’s not Investing and certainly not Investing Wisely.
The problem for Investors is that they have for decades, for the most part, considered themselves to be Buy and Hold Investors, (married to the stocks and mutual funds) through both good times and bad. When they finally get discouraged, (and they do!)they get out, usually due to large losses, and they tend to stay out for very long periods. An excellent current example is / are those who have been on the sidelines since the big bear market plunge of October 2007 through early last year, not enticed back in for even part of the new bull market of last year plus.
They (Mutual Fund Investors) tend to listen to Wall Street saying they need to have a long-term perspective when their stocks and mutual funds are plunging 25% - 50% and more, and so hold on. When they do decide to ‘reposition’ their portfolio they tend to listen to mutual fund managers, and brokerage firm sales persons and spokesmen on TV shows and in magazines, advising them to buy a stock that should be 30% higher 24 months from now, without considering that it might first be 30% lower three or more months from now.
