Answer #1

Risk is measured by Beta and beta can be determined with the help of Standard Deviation. Beta more than 1.0 is volatile and less than that is less volatile. The more volatile the stock price, the more risky in nature it is. Holding period is when you hold an asset or a portfolio over a period and expect a return on it. Now the connection in between holding period and risk volatility is that, holding a stock for a longer term could alleviate any temporary volatilities that takes place in the business or the market. Portfolios are designed in a way that average returns and standard deviations benefit the overall returns over the period to the investor. Risk may grow along withe holding period only when the stock performance is consistently proving to be a failure, not in the case of consistently performing well.
