Insight from TheStreet's Research Team:

Bryan Ashenberg and Bob Lang have identified Herbalife as the Chart of the Day. Here is what Ashenberg and Lang had to say about the stock's chart:

The battles between activists Carl Icahn and Bill Ackman are legendary, and for sure, the controversy over Herbalife (HLF) - Get Report has been noted.

Yet, the stock continues to power up, nearly hitting a 52- week high yesterday in the worst tape imaginable. Despite the potential risks to shareholders, including accusations by Ackman that the company is a ponzi scheme, Herbalife's stock performance is impressive.

The chart shows a very tight range as Herbalife grinds higher. Note the nice relative strength, and the %R just gave a buy signal on a bull retest last week.

Volume trends have been good of late but it is that relative strength in the top pain that really impresses. We could see more upside here in the days ahead.

Separately, TheStreet Ratings team rates HERBALIFE LTD as a Hold with a ratings score of C. TheStreet Ratings Team has this to say about their recommendation:

"We rate HERBALIFE LTD (HLF) a HOLD. The primary factors that have impacted our rating are mixed, some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks. The company's strengths can be seen in multiple areas, such as its increase in net income, expanding profit margins and growth in earnings per share. However, as a counter to these strengths, we also find weaknesses including weak operating cash flow and a generally disappointing performance in the stock itself."
