Resistance An effective upper bound on prices achieved because of many willing sellers at that price level.
Resistance. Resistance, or resistance level, is the top of a stock's current trading range, and the point at which the price is higher than investors are willing to pay. As stockholders sell at resistance level, the stock price goes down because supply exceeds demand. For example, if, on a repeated basis, as stock A's price reaches $60, stockholders begin to sell, then $60 is considered its resistance level. But a trading range isn't fixed and investor attitudes change, so the resistance level tends to move higher or lower over time. If stock A rises to $63 without a surge of selling, the current resistance line has been breached. This may be the result of a rising market or a bullish assessment of the stock's value. On the other hand, if selling increases at $57, that may become the new resistance level. Conversely, the level at which demand exceeds supply and investors typically buy a certain stock is called support. It's the point that's considered the bottom of a stock's current trading range. Technical analysts use the concepts of resistance and support in anticipating future stock price movements. How to thank TFD for its existence?

The data being presented today support the lack of cross resistance between satraplatin and the two taxanes that are currently approved for use as chemotherapeutic agents in the treatment of human cancers - TAXOTERE and TAXOL," said Marcel Rozencweig, M. In light of the broad sensitivity of human ovarian tumor cell lines to ZD9331 and its lack of cross resistance to platinum based drugs, there is a strong rationale to expect this combination to be effective in treating advanced ovarian cancer patients," said Prof. |
