Wall Street has another explanation as to why the stock market is on fire, which may help investors understand the possibility of some tech stocks winning red hot. This gamma – a mysterious factor in the pricing of stock options that is not talked about much.
According to the Wall Street newsletter from the bear trap report published on Tuesday, Wall Street has very little gamma, and it messes up brokers’ hedging strategies. This could partly result in rapid growth in some stocks, including Tesla and Apple.
Gamma typically has to do with stock option pricing – which is the domain of the deep-pressed options trading desk within the brokerage equity divisions.
Gama is one of the so-called “Greeks” – from Greek letters – traders, and investors, helping value options as well as rescue departments. Understanding the Greeks can help investors understand the recent trading action. There are five ancient letters to know, but we will focus on delta and gamma.
- Delta: This is how the price of a stock option changes to the underlying stock price. If a stock becomes $ 1 and the option price changes by 65 cents, the delta is 0.65. The delta is generally less than one.
- Gamma: In this way the delta changes. There is no rule that the delta of a stock is fixed. things change. And factors such as premature expiration and option strike price can affect gamma.
If the delta of a stock is 0.5, then only 1 share is required for every 2 call options sold to a broker. If a stock becomes $ 1, the broker has a profit of $ 1 on the stock and a loss of 50 cents on each option. In that scenario no daily gain or loss arises. Don’t forget, when brokers sell option contracts, they don’t want to risk what happens to the underlying stock. Brokers only want to sell a commission – and trading – option.
But if the delta jumps to 1 out of 0.5, the broker needs another share of the underlying stock to compensate for the loss of the option. So gamma can generate more growth in the underlying stock than expected, such as
(Ticker: TSLA) or
Rising Gamma is a possible explanation as to why those two huge stocks are making huge gains. Tesla and Apple shares are up 70% and 25% respectively from the previous month, of which comparable returns have been received
Dow Jones Industrial Average
On the same span.
Changes in Apple and Tesla Delta – Gamma has gained momentum in recent weeks. Still, the gamma explanation is not speaking to everyone on Wall Street. Some options reflect traders Baron’s It is impossible to know how people are hedged.
There may be a risk of seeing a factor that is coincident with a stock move such as Gamma, but it is not actually the cause of the stock move. It seems that the runny nose is the cause of a cold. A runny nose is a symptom, but not an underlying cause. For example, Tesla stock has been rising lately due to good results, raising the price target of analysts. Higher gamma may be a consequence of a fundamentally driven stock price run.
Apple’s recent run-up may also be partially due to the same gamma dynamic. But like Tesla, other factors may also come into play with Apple, such as high expectations for the launch of its 5G iPhone.
In the stock market, trading activity often forgets more trading activity. Option trading and hedging is one reason that is true. So there is fear of missing out – investors hate missing big profits.
Interested to know about three other ancient letters to know, here you are:
Theta: Stock options have value, due to time. The more valuable option has more time to expire, as the option is more likely to run out of money. There is a decay in the time value of the theta option as the termination approaches.
Vega: This option measures changes in pricing as the stock becomes more or less volatile. More volatile stocks have more expensive options. When a stock swings wildly, the profit is more likely to sell a put or call option.
Cry: Investors still running side by side are still in mourning. The RHO measures the sensitivity of option prices to interest rates.
