Quantitatively, WFC's earning power is as follows:
1. Pre-tax and Pre-provision revenue $40 B per year.
2. Assuming 1.5% charge-off of $800 B loans (currently at 2.7%), annual charge-off is $12 B
3. Assuming 35% tax rate, net profit is $18 B and is $3.65 per share.
The above number should be well known since Buffett first mentioned the $40 B figure and WFC is at the mark as of 2009. The threshold for WFC to reach above goal should be low in about one or two years. So, WFC should be a $40 per share stock.
The reservation by market is probably due to following factors:
1. Impact of second dip or prolonged recession and thus second financial crisis.
2. Commercial real-estate crisis.
3. Higher interest rate.
4. Issues of integrating Wachovia.
5. Reduced balance sheet and thus earning power.
Issue number 1 has probably the most weight as it threatens the survival or earning power of WFC. Plus, WFC's capital ratio is not rock solid as of today. Its reported earnings of MSR in the scale of $1 B per quarter is not sustainable.
Regardless of all the issues, Buffett definitely thinks the earning power of WFC is strengthened rather than reduced in this crisis. Of course, his remarks carry less weight now than before.
Based on the above, the volatility of WFC's stock price may be back to normal and thus fewer chances for speculation. Personally, I am holding WFC stock long-term but also writing 1-year deep out of money calls, 1-year mediumly deep out of money calls and monthly shallow out of money calls.
My positions are unprotected as the chance of WFC going below $20 is low and Buffett's position should exclude qualitative company risk in WFC. The latter fact means significant dip of WFC represents opportunities rather than risks. The covered calls yield quite nicely and hopefully will keep doing so before WFC's stock price is normalized to above $35.
