Quote from lescor:
Some better assumptions in those recent posts. First of all, as I've posted before, some people, probably new traders or those who don't trade equities, assume that stocks move tick for tick with the market. Simply not true. Mike is right, 50 individual long stocks worth X$ is not the same as X$ worth of spy.
In a nutshell, I'm trying to buy stocks at a discount to the market and sell those that are overvalued. The median line on what I consider under or over valued is my own assumption, or proprietary calculation if you like. So if I buy a stock at a discount, and hedge it with a spy short, I want the spread between those stocks to narrow, irregardless of market direction. It's not a net zero position. There are many factors that go into when or by how much I hedge. Volatility, time, total exposure, valuation, sectors, etc. This is all pretty simple spread / arb stuff or whatever you want to call it. A million guys are doing stuff like this, just that everyone has their own way of applying it and how they operate. And yes, in a high volatility, fearful environment, on expiration day to boot, things get more out of line and the profit margins go up accordingly.
Quote from Rehoboth:
Mike has this correct. Closing out stock does not mimic what lescor is trying to do. He has positions that will outperform the market for a given time frame. If the market had gone down, those positions will have also gone down, just to a lesser extent then the SPY.
Lescor probably has a atr/beta/dollar netural spy amount per position that he enters. So he would probably not be dollar neutral, but market neutral based on his system.
So Lescor,
Are you "pairs/spread trading" with the SPY? ...

Quote from austinp:
Let me articulate concisely: to "hedge" something literally means freeze its current value from decay or appreciation alike. You cannot "hedge" something from further loss while preserving total gain regardless. The only way to do that is by placing fixed exit stops to prevent loss from a specific point. Anything else is nothing more than an offset spread.
Whatever x-amount of beta lescor hedges with lower-beta spy is exactly the same, identical result as closing out that amount of estimated beta in the first place. Yes, I understand all the variables involved, etc. I assumed we all had a similar understanding when I wrote before.
Bottom line is this: hedging or closing/opening trades has nearly identical results in the end. There is a great misconception that to "hedge" means cap further loss while preserving total future potential gains. Not true. A hedge spreads off risk at a cost of further reward from there.
Quote from Rehoboth:
I still disagree with everything above. Hedging is about reducing risk, not about reducing reward. The reduction in reward is usually the consequence.

Quote from austinp:
well, you have every right to disagree. but the fact remains same: to hedge risk is to reduce or remove risk. when taking an opposing trade in something that affects the open trade, what you have effectively done is closed part or all of the initial open trade and/or its favorable leverage.
hey, there are many people out there who actually believe they can be long a symbol in one account, short in the other and have two open positions hedged. trying to explain that they have no position in the market with an open short and open long sails right over their heads
