You can time the market.

    Not going to debate whether mkt can be timed (read / deciphered / traded)

    Indicators are based on PA - if indicators can be "gamed" as you say - then the PA was there to read / decipher / act upon - in the first place

  2. When then trading guru pundits on CNBC say buy buy buy they typically are right but not because they know what they are talking about... The optionality for guys publicly calling the market is better to call for a rise then a fall....

    There's nothing about the SP500/300dma crossover that looks "grailish". But a backtest would reveal whether it was truly profitable long-term (newwurldmn indicates otherwise) and might even help reveal what the optimal MA crossover parameters would be. Untradeable info of course --you can't trade the past-- but perhaps useful in other ways.

    Yes, and who is debating
    You failing to follow, if I wanted, I could come up with a crossover that looks great, just to impress or fool.

    I am amazed that no one challenged my backtest results. I reran it, this time simulating a portfolio that would generate compounding vs the arithmetic returns I did this AM.

    The strategy outperformed over the last 85 years. I also ran it from 1995 to today. The strategy outperformed, but for vast periods it was significantly underperforming. The strategy only works if there is prolonged period of a down market. Otherwise it gets whipped around. Even with the outperformance (from 1995 to today it returned 4.5x initial investment vs 4x for the buy and hold), it's unclear if you would do better given the additional taxable events created and dividends you would forgo during your short periods.

    If we rally back to the 300d MA in the next few weeks, this strategy will underperform this go around as well.

    Yes, MA crossovers are crude tools, which is why their users get killed in chop. And most traders never get beyond the crude-tool stage, be it crossovers or breakouts. But with the right trading instrument(s) and some luck, even crude tools can get them to the finish line.

    If you apply the 300 MA on the Nikkei from 1984 till today you will bearely break even (3.52% profit before slippage, commissions....). This proofs that the 300 MA is a bad system. A good system should not work on only one index, it should work on all indexes.
    The 300 MA is optimized for the S&P, and in 5 years the best MA will maybe be 122 days. Don't understand why real traders work with MA's. I even know "traders" that optimize MA's every day.

  9. when i look at the graph, all I see is confirmation bias.

    There are several crossings below the 300 MA line which haven't been followed by selloffs.

    As others also said, you have to define 'strongly'. Otherwise you're still left with a nondeterministic algorithm for timing the market.

  10. FYI: I back tested a simple start with $100K, and buy SPY when Close above 300 day SMA, and exit trade when Close below 300 day SMA, and show the results below. Note: If one were to actually consider such a trade, it would be wise to add some filter or hysteresis to prevent rapid whip-saws.
