SPY Losing Assets As It Rallies

Jason Goepfert
2019-02-19
null

One of the charts pinging around Finance Twitter shows cumulative ETF flows in SPY ebbing even as the fund rallies. That certainly has been the case, and it certainly is unusual.

If you scroll through the comments on that Twitter thread, not something I would usually recommend, they are almost uniformly bullish. Investors think that this is evidence of a "wall of worry" and should lead to higher prices. Historically, though, that has not been the case.

The tables below show every time in its history when SPY rallied to at least a 16-week high and its cumulative ETF flow sunk to a 16-week low. The second table shows times after even more extreme outflows.

Both show weaker-than-average returns for SPY going forward, up to one month later.

Risk Disclosure: Futures and forex trading contains substantial risk and is not for every investor. An investor could potentially lose all or more than the initial investment. Risk capital is money that can be lost without jeopardizing ones’ financial security or life style. Only risk capital should be used for trading and only those with sufficient risk capital should consider trading. Past performance is not necessarily indicative of future results.

Hypothetical Performance Disclosure: Hypothetical performance results have many inherent limitations, some of which are described below. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown; in fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. One of the limitations of hypothetical performance results is that they are generally prepared with the benefit of hindsight. In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk of actual trading. for example, the ability to withstand losses or to adhere to a particular trading program in spite of trading losses are material points which can also adversely affect actual trading results. There are numerous other factors related to the markets in general or to the implementation of any specific trading program which cannot be fully accounted for in the preparation of hypothetical performance results and all which can adversely affect trading results.
