In running a very tight stock screen recently for value plays Burlington Northern Santa Fe (NYSE: BNI) showed up on a list of 14 stocks. Interestingly all the large railroad stocks did. This reminded me of several stories I have done on the subject, the most recent being Chasing Value: Watch BNI -- the heck with Citigroup.

To summarize, about six weeks ago a Citigroup (NYSE: C) analyst declared it was time to sell the stock when BNI was trading in the mid $60s -- I said investors should do the opposite, it was a great value. Friday the stock closed at $76.98. Even at this price it is a value and ever more so with oil prices steadly creeping up.

It is not possible to know what level is the right level to enter the stock market and various analysts, gurus, journalists and economists have been weighing in this week as the market closed at a one month high, with some folks even becoming downright optimistic.

I might add that the true level we have reached is one of amusement to me because we all are trying to call the market bottom. I myself have entered the fray trashing Nostradamus along the way. This is as much hope, as fact, and folks are looking for clues everywhere.

Some are looking at historical precedent for clues. Technical analysts are combing their charts for patterns of market behavior. The uptrend has to be sponsored to some degree by short covering and momentum traders too.

Positive news was reported by Wells Fargo (NYSE: WFC) which said on Thursday, April 9 that it expects to post a record first-quarter profit of $3 billion, up about 50 percent from a year earlier, due to better-than-expected performance from Wachovia (acquired in December) and a strong performance in mortgage lending. This was all it took to send the market higher even before anyone has actually sifted through the quarterly report for themselves -- not due out until April 22.

I am not surprised that the market is up and I have been putting cash to work for the past six months; but not all at once; not without recognizing that I might be early; and not without a plan. This has included buying WFC most recently at $12.00 and selling naked puts at strike prices of $7.50, $9.00 and $12.00. My most recent post on the subject from last month was Chasing Value: The safest bank in the U.S. -- Wells Fargo.

If you have missed the recent market pop do not fret and do not chase it because it could change direction as many have called this a bear market rally.

What might be most prudent at this point, if you believe that the volatility will continue and the stock market will not see true lasting improvement for a while, is to segment the money you want to put back to work into four or five tranches and invest on a regular basis dollar cost averaging back in over time.

Periodically, a beginning investor reader will ask how to decide on which stocks to purchase. The easy answer is that beginning investors have no business investing in individual stocks. Beginning investors should be investing in mutual funds containing diverse offerings that decrease risk. Or, beginning investors should invest in exchange traded funds, ETFs, which are collections of stocks around a central investment goal or risk factor, but unlike mutual funds, ETFs trade on stock exchanges and are fully liquid.

All that being said, investors who want to purchase individual stocks in their own name, would do well to investigate publicly traded companies that offer dividend reinvestment plans, or DRIPs.

DRIPS are an extension of employee stock plans that larger companies have long offered their employees, but are now also open to the investing public.
