The term âWIMPâ is given to a dark matter particle that was produced by falling out of thermal equilibrium with the hot dense plasma of the early universe, although it is often used to refer to any dark matter candidate that interacts with standard particles via a force similar in strength to the weak nuclear force.ts name comes from the fact that obtaining the correct abundance of dark matter today via thermal production requires a self-annihilation cross section of, which is roughly what is expected for a new particle in the 100 GeV mass range that interacts via the electroweak force.
Market capitalization. Market capitalization (market cap) is the market value at a point in time of the shares outstanding of a publicly traded company, being equal to the share price at that point of time times the number of shares outstanding.
For example, a company with a stock price of $60 and 100 million shares outstanding (a market cap of $6 billion) is actually smaller in size than a company with a stock price of $25 and 500 million shares outstanding (a market cap of $12.5 billion).he smallest of the small-cap stocks are called micro-cap and nano-cap stocks. Micro-cap stocks ($50 million to $2 billion in market capitalization) and nano-cap stocks (market caps less than $50 million) are even riskier than small-cap stocks.
