Stocks in the healthcare sector are affected by various factors, but they tend to be recession-defensive because health is essential to life. In this article, we look at a healthcare sector trading strategy.
The healthcare sector might add diversification to your portfolio of trading strategies. The reason is that many of the stocks in this sector is what we can call “recession-proof”. They are, of course, not immune to a recession, but their business model tend to be less elastic to the overall economy. Thus, the sector is often labeled safe haven investing.
What is the S&P Healthcare sector?
The S&P 500 Information Technology sector consists of those companies included in the S&P 500 that are classified as members of the GICS information technology sector — a group that includes different industries like pharmaceuticals, biotech, health insurance companies, hospitals, and health device manufacturers. Now, we also have the cannabis companies, which are rapidly growing, as a part of the health care sector. The popular ones include Canopy Growth Corp. and Aurora Cannabis, with market caps of $23 billion and $12 billion, respectively.
Popular ETFs that track the healthcare sector include the Vanguard Health Care ETF (VHT) and the Health Care Select Sector SPDR Fund (XLV).

Healthcare sector trading strategy
We show you a seasonal trading strategy. The good thing about healthcare stocks is that they have different properties than the “overall market”.
We have made a rotational strategy that twice a year rotates from S&P 500 and the ETF with the ticker code FSPHX.
Why do we use FSPHX? Mainly because we get data back to 1981 – much longer than any ETF (XLV) on the market. Second, the fund holds a pretty diversified portfolio of healthcare stocks.
If we backtest by using the ETF with ticker code SPY (which includes dividends) since 1993 we get this equity chart:
The CAGR is 14.25% and the drawdown is 50% in 2008.
Buy and hold for the S&P 500 (SPY) was 10.3% during the period.
The difference in the compounded result is enormous: from 1993 until June 2021 the rotation strategy ends up with 4.45 million, while buy and hold SPY only ends up with 1.622 million.
Just “small” differences add up over time, although 4% more per year can hardly be called small.
