The weak form of the emh states that All past information, including security price and volume data must be reflected in the current stock price.
What is the EMH?
The efficient market hypothesis (EMH), also referred to as the efficient market theory, is a theory that holds that share prices accurately reflect all available information, making ongoing alpha generation impractical.
It is impossible for investors to purchase discounted stocks or to sell them at inflated prices, according to the EMH, because equities always trade on exchanges at their fair value.
According to the weak version of the EMH, the current stock price must reflect all past data, including security price and volume information.
Because of this, it should be challenging to outperform the market as a whole through expert stock selection or market timing, and the only way for an investor to see higher returns is to invest in riskier assets.
So, according to the weak form of the EMH, (A) the present stock price must reflect all historical information, such as security price and volume data.
