Most who understand how to Hedge will not post about how it is done period. Most won't say how or why or how well it is done. I been hedging Commodities since 90s and cause of my style of very long term commodities, have to hedge as I am seeking the extremes on charts to go against immediate trend. I started like most Retail does, didn't like to lose at some point and using options to hedge made sense, like any faucet of any business you find tricks as months/decades goes by, and when you discover something, never discuss it. I hedge anything that won't be a day trade whether stocks/commodities.
There are still few areas of trading much of retail never considers cause of steep learning/knowledge that it entails like Spread trading and much about using options. Trading is about keeping an open mind and very long hours testing ideas.
Large traders and firms will use the futures to hedge their dividend stocks, they might have bought stocks in 2009 and all paying dividends, so when you get over extended market, they long millions of stocks of certain value, and go short large or Emini S&Ps futures of equal/less/more of value in hopes that correction ends and they will lift their futures position or even reverse the futures and make more on profit of futures, whereas the hedge was so as not to loss value on the stocks but retain dividends. They might do a double Hedge of going short the futures and do Call options in case they were wrong in timing, all kinds of different ways to hedge and different times of putting them on. They can sell the futures and sell OTM call options, many approaches depending on their backtested models.
Most get it wrong on hedging, it lowers risk, smaller drawdowns and done right, well.......you just going to have to work on for your answers.
