Stocks to the Rescue

WIth oil down again, my funds performed poorly. However, my stock holdings which represent 26% of my portfolio, increased 1.78% today alowing me to beat the major indexes quite easily. Right now, I'm looking for a boost in oil given the forecast for the first major outbreak of cold weather in the northeast as an opportunity to sell my energy fund and decrease my mutual fund holdings.

While I'm always on the lookout for new stocks to buy, right now I'm focusing my attention on increasing the size of some of my individual stocks to increase their weight in the portfolio. Im currently buying ARTX, PXPL, ATRM, and RAND on any weakness they show.

Buffett's Value Formula (?)

Warren Buffett hasn't exactly published his formula for what he calls the intrinsic value of a company, but he has dropped a number of hints. He apparently multiplies estimated future earnings by a confidence margin between zero and a hundred percent (a bird in the bush being worth 0.5 birds in the hand, and all that; bush birds are the earnings you hope for, and hand birds are the earnings you're confident will materialize). He then compares these probable earnings with something he has total confidence in, by using a U.S. treasury yield as his discount rate. In calculator form it looks like this:

 

Earnings
Earnings per share (last 12 months): $
Growth Assumptions
Earnings are expected to grow at a rate of % annually
for the next years,
before leveling off to an annual growth rate of % thereafter.
Confidence Margin
How confident are you that these expected future earnings will really materialize?   %
Discount Rate
Best available return that you have 100% confidence in (like a Treasury bond):   %
 
Results
Stock Value per share: $

 

       This calculator doesn't use fancier math than the original one did. Its advantage is that it forces you to be explicit about your earnings expectations. It also automatically provides you with a hard-headed investment strategy: always invest in government bonds, unless you can find something else you are confident will yield more cash.

One other hint that Buffett has dropped over the years is that he can estimate value in his head in about five seconds; so whatever he does he keeps it simple, slugger.
