What is SYNTHETIC LONG CALL strategy?
Strategy: Buy Stock + Buy Put Option. This is a low-risk strategy. This is a strategy which limits the loss in case of fall in markets but the potential profit remains unlimited when the stock price rises.
For example, investor/trader purchases a stock (bullish view) and buy a Put option of the stock. The put option will compensate losses against long position in case the market goes down, thus acting as an insurance. Mr. XYZ is bullish about State Bank of India (SBI) stock. He buys SBI future, or in cash at the current market price of Rs274. To protect against fall in the price of SBI, he buys SBI Put option with a strike price of Rs270 (OTM) at a premium of Rs7, expiring on March 28.

How much would be the maximum downside if the price falls?
The downside is limited.
Formula: Stock price + Put Premium – Put Strike price. That is, 274+7-270 = 11. The worst that can happen is that the stock would become worthless. Let us suppose, on March 28 expiry, the stock closed at 230, then the loss on the stock is compensated by the gains in put option.
Breakeven Point: Put Strike Price + Put Premium + Stock Price – Put Strike Price.
