Realise that no one knows where the market is headed
The fact is, no successful investment strategy revolves around trying to guess the market's direction, so I wish everyone would just stop acting like that's a productive activity. Now, maybe there's some guy running a hedge fund in London who has been able to call the highs and lows in this or that market with some regularity in the past, but I'd question his ability to do so in the future, and chances are the onerous fees he's charging will get the better of his returns in the long run. The mutual fund landscape provides compelling evidence that using a so-called "macro" strategy doesn't work: Managers have been so unsuccessful at calling the market's direction that 99% don't even try.
Now, I know that I can't convince the legions of pundits and brokers of the merits of not producing the noise. After all, their livelihoods depend on getting you to trade and buy stuff based on the daily news flow. But if I can convince you, Mr. or Ms. Small Investor, to tune it out, I'll be satisfied.
Simply follow these steps. As you do so, take note of the fact that NOT ONE of them involves formulating a view of the future direction of the market.
