虽然技术上有调整压力，但从日线图均线金叉，P/C的比例变化，市场情绪来看，短期向上（可能有波动, DIP是机会), 中期向上.
无论从FA和TA看, 当下的形势可去年大不相同. 美国的经济形势改观有助于市场情绪稳定看多.
The P/C Ratio is derived by dividing the total number (volume) of option put contracts purchased by the number of option calls, for a given trading day. For those unfamiliar with options trading, options are contracts that give the purchaser the right, but not the obligation, to buy or sell a security at a specified and guaranteed price, called the "strike price." Options to buy are called "Calls," while options to sell are called "Puts." The option buyer can exercise their option so long as the underlying stock or index has achieved or bested the strike price no later than the day of expiration. Calls, therefore, imply the buyer is optimistic (bullish), whereas Puts imply the buyer is fearful of, or anticipates, a decline (bearish).
The P/C Ratio thus measures the degree of bullishness or bearishness in the market, based on the ratio of Puts purchased to Calls purchased (i.e. Daily Put Volume/Daily Call Volume = P/C Ratio). The Chicago Board of Options Exchange (CBOE) calculates the P/C Ratio for all equity and index options traded in their Daily Market Statistics. Traditionally, a P/C Ratio of .80 or greater is considered bearish. Readings above 1.00 over a number of trading days are considered strong signs of a market bottom. Below 1.0, the readings are considered neutral in the .40-.50 range, and extremely bullish at readings below .30. The lower readings are considered strong signs of a topping market nearing a reversal. Note that technicians regard extreme high or low readings as contrarian signals. The value of the Put/Call ratio is thus in determining when sentiment extremes have been reached, as such extremes tend to give way to their opposite. |
