• ZYME shot back up 6.4% today.
• Retyping old investment notes for memory:
• Most common index funds: S&P500, DJIA (30 large cap), Russell 2000 (small cap).
• Mutual funds are not traded on exchanges, like regular stocks. They are pools of money that are collected from investors, then the asset managers choose the underlying securities for highest growth. Mutual funds are both an investment and a company.
• ETFs are exchange traded funds that you CAN trade like any regular old stock, and they track underlying index funds.
• Bull. Good. Rearing horns UPWARD. Bear. Bad. Swiping claws DOWNWARD.
• Money market funds are in things like government treasury bonds. Very low risk, low return (like a CD, little better than savings account).
• SPY is the ETF for S&P500, DIA is the ETF for DJIA.
• Hedge. Complement an investment with the opposite to reduce risk (and gains). Example: buy 1 stock for $100 and buy a $80 put option (year) for $5. If it goes up, you lose the $5 insurance policy but if it goes down, you can sell for $80 instead of $0.
• Derivatives are assets based on other assets, like a futures contract to hedge an initial buy, or options. They aren’t stock, but are derived from stock.
• Options. ISOs are like call options, buy at strike price and hope it goes up. Put options hope it goes down. If it drops, you buy the shares at the lower market price, then force the original contractor to honor the options and buy them from you at the higher price. Options have an expiration. Usually 1 put/call is for 100 shares, so a 50/50 hedge would be to buy 100 shares and buy 1 put.
• Futures. Like options, just an agreement to buy or sell at a future date, but you HAVE to fulfill the transaction. This is commonly done for raw materials to hedge.
• Shorting is betting on decrease. A put option is a short, a short position in futures is a short.
• Straddle. Buying a put and call option at the same strike/expiration. You profit if the price moves sharply in either direction.
• EPS = earnings per share. Not normalized, because a company can have an arbitrary number of shares.
• P/E = price earnings ratio. Normalized. Just the current price/eps. S&P is about 15. Higher doesn't necessarily mean better; it can mean overvalued.
• Sharpe ratio is the risk-adjusted return. Basically take your average return (usually daily), subtract the risk-free return (usually 0), then divide by the standard deviation of returns, then annualize.
• Football scrimmage.
• False start = offense moves, ball is not hiked.
• Neutral zone infraction = defense moves, ball is not hiked.
• Encroachment = defender touches offender, ball is not hiked.
• Offsides = ball is hiked when defender is past line, free play.
• Remember belly breathing and 4-7-8.
