If you have been scanning today's entries, or the financial news in general, you have seen a number of brokerage stocks mentioned. The "buy-under" at Bear Stearns (BSC) has that stock plunging and is raising concerns in general. Given the turmoil, I thought it might helpful to take a look at TD Ameritrade Holding Corp. (AMTD), E-Trade Financial Corporation (ETFC), Lehman Brothers Holdings Inc. (LEH), and The Charles Schwab Corporation (SCHW).

Let's start with the Street's opinion, according to Zacks:

• 6 of 9 analysts (67 percent) rank AMTD with a "buy" rating
• 0 of 10 analysts rank ETFC with a "buy" rating
• 7 of 13 analysts (54 percent) rank LEH with a "buy" rating
• 4 of 11 analysts (36 percent) rank SCHW with a "buy" rating

Now, let's turn to the weekly charts...

Shares of AMTD and SCHW are holding intermediate-term support. If the both stocks stabilize here, it would leave TD Ameritrade continuing its sideways meander and Charles Schwab in its long-term uptrend.

Shares of LEH and ETFC are both trading below support. However, the situation with E-Trade appears to be somewhat different that what Lehman Brothers faces. E-Trade was hit with its much publicized woes last year and the stock appears to be trying to base. The shares hit a low in early January and are still holding above that level.

Meanwhile, Lehman is in the midst of a hard-break down. Its shares are hitting short-term oversold levels (which could support the case for a short-term bounce) but that former support near 50 now looms as overhead resistance.
