Picking individual stocks is a bit like backing one horse in a 500-horse race. You might pick well. You might not. And often, you only know after the race is run.

The S&P 500 gives you the whole field.

It holds 500 leading listed companies in the United States — including Apple, Microsoft, Amazon, NVIDIA, JPMorgan and many more — across sectors such as technology, healthcare, financials, energy and consumer goods. When you buy SPY, the ETF we use in the 80DELTA system, you are not relying on one company to get everything right. You are gaining exposure to a broad slice of large-cap U.S. equities.

Why That Matters for Risk

If you own a single company and that company has a bad quarter — or worse, a bad year — your portfolio feels the full impact. A profit warning, failed product launch or management issue can send one stock down sharply in a matter of days.

With SPY, that company-specific risk is diluted across a basket of 500 stocks. Diversification does not remove market risk, but it does reduce the damage that any one business can cause on its own.

It also works in the other direction. You do not need to identify the next big winner in advance. The S&P 500 is market-cap weighted, so as companies grow and become more influential, their weight in the index rises as well.

Why SPY Specifically

There are several ETFs that track the S&P 500, but SPY is the one we use in the 80DELTA system for a reason.

SPY is one of the largest and most heavily traded ETFs in the world, with a very active options market around it. For Australian investors, that liquidity matters. It generally means tighter bid-ask spreads and more efficient execution when running our Income Engine through covered calls and our Protection Engine through long-dated puts.

In practical terms, tighter spreads can help reduce trading friction when entering or exiting positions. That becomes especially important in a system that uses options regularly.

SPY also offers a wide range of expirations, including standard, weekly and additional weekday expiries, giving us flexibility when selecting strikes, timing entries and managing risk.

Long-Term Market Exposure

There is also a broader reason we anchor the system to the S&P 500: it has historically provided strong long-term exposure to large-cap U.S. equities.

Over long periods, the S&P 500 has produced average annual returns of about 10% before inflation, although returns vary significantly from year to year and past performance is not a guarantee of future results.

That is the foundation the 80DELTA system is built on. We do not need to predict which individual stock or sector will outperform next quarter. We need a liquid, diversified, long-term vehicle that we can layer income and protection strategies on top of.

SPY gives us that.

The Bottom Line

The result is a simple foundation: diversification, liquidity and broad long-term market exposure — all in one ticker.

That lets us focus our effort where it matters most: running the Income Engine and the Protection Engine, rather than trying to pick individual stocks in a market where single-company outcomes can be unpredictable.

That is why we use SPY. That is why we use the S&P 500.
