Benjamin GrahamWHAT IS MARKET VOLATILITY?
Volatility is the degree of variation
in a trading price over time. It is
measured by looking at the
standard deviation of returns—
that is how spread out returns arefrom an average value. Lower
volatility means a share’s price
does not fluctuate dramatically,
but changes in value at a
steady pace.❯❯Lump-sum investing Although high
returns are possible, putting large single
sums into the market tends to require a
more impulsive, or short-term approach,
which may be counterproductive.
❯❯Market conditions Dollar-cost
averaging means investors do not have
to study the details of market behavior to
maximize their returns.
❯❯Investments from income By regularly
investing directly from regular income,
investors can keep cash on hand for
other purposes or emergencies.NEED TO KNOW
