I completely agree. The conventional wisdom of buy and hold a diversified portfolio of stocks and bonds or index funds is simply bad advise right now.
While stocks do tend to out-perform over the "long-term" there have been multiple 10 year periods when stocks lost big in terms of real inflation adjusted returns. (e.g. 1929-1960, 1971-1983, 2000-present)
As a primer on the current financial crisis, I recommend firing up your favorite search engine and reading up on:
* inflation: understand that inflation is not rising prices, it is inflation of the money supply and debasement of the currency
* fraction-reserve banking and fiat currency (understand the leverage built into banks and financials and its impact on the broader economy)
* petrodollars and their importance to the US economy's ability to run deficits and import it's inflation as well as the rise of the Euro and the opening of Iran's oil bourse with it's promise to trade oil in all the world's currencies.
Other posts have listed some great resources, here are some general tips from personal experience:
* Stick to the classics and understand fundamental valuation
* Remember, there is something to technical analysis for short-term trading and market timing, but most of it can be explained by thinking about the supply/demand situation for a specific stock or asset class. Don't get sucked into the voodoo.
* learn to think about stocks and asset classes in marketing terms (branding, awareness, interest, trends, etc.) and you will gain a big edge over most. If you can figure out where the money is flowing and why within market segments or individual stocks, you stand to outperform.
* invest in what you know. find companies you are interested in and learn their investment story. Read their ipo prospectus if it is a new issue or their last 2 annual reports if they are established.
* never accept a stock tip without an explanation of the investment thesis behind the stock. Do your own research and be able to explain why you hold specific positions.
I am an entrepreneur and as such am generally an optimist. However make no mistake, there are clear and significant downside risks to this economy. There is more downside risk than upside potential over the next 6-12 months and possibly longer. The next 12 months will be an education in itself.
