Let's take a look at what other CAPS members are saying about a couple of these stocks and whether they agree with this player's assessment.

Degree of risk
The stock of CardioNet, which makes wireless heart monitoring devices, went into a tailspin recently when the company confirmed that Highmark Medicare Service was cutting Medicare reimbursements by 33%. Some analysts think CardioNet may need to restructure, but enhancements it has made to its mobile cardiac outpatient telemetry services may help it negotiate payments that more appropriately value its technology.

CAPS member BetapegLLC believes it has tremendous potential:

The stock price is only 11% more than book value and investors pay only $1.25 for every dollar of sales. Estimated earnings growth is also undervalued as indicated by a PEG ratio of 0.38. CardioNet has outperformed 8% of the market in the last 8 months. This indicates the stock to be highly undervalued relative to its fundamentals grade of 53%. CardioNet is valued at $32.91 for FY2009. With a current price of $7.28, BEAT is 352.11% undervalued for the fiscal year. Insiders have purchased and granted a substantial amount of shares indicating executives see great potential in the stock. The Company has an excellent balance sheet with many times more cash than short-term debts in addition to having no long-term debt.

Not to its credit
Here's a shocker: Wells Fargo is making interest rates higher for most of its customers ahead of a rule change that limits such increases. Wells Fargo says it has nothing to do with the new law -- rather, it's because of the continuing deterioration in business conditions.

It was anticipated that many banks would stick it to their customers with higher bill payments, so Congress is now considering changing the compliance date for banks from February to December. Bank of America (NYSE:BAC) is noteworthy because it said it would not raise its rates.

Wells Fargo has otherwise shown itself to be a well-run institution, and analysts see its Wachovia acquisition as a long-term driver for growth. Yet as the third-largest bank in the country in terms of deposits and market cap, Wells Fargo probably doesn't offer investors the same sort of growth that it did in the past. Foolish colleague Alex Dumortier still sees Wells Fargo as a buy at these levels, and CAPS member AZBrewer concurs:

Still bank is well run and under-exposed to the toxic assets of residential and commercial real estate relative to their peers. However, their acquisition of Wachovia and it's portfolio of toxic assets will promise some pain in the short-term. Look for this company to lead the pack out of this crisis.
