It seems like investors were writing off the real estate sector entirely.

With the rise of technology used to shop online, work from home and even go to school, real estate has been a hated sector.

But it’s a sector I have been a fan of this year, triggering gains of 15% and 17%.

That’s because even though I know the landscape for real estate is changing, I still see the crowds at the malls, the wait times at restaurants and the continued need for hospitals and healthcare facilities.

So the decline in values recently has looked like an opportunity to me.

But my personal experience or viewpoint doesn’t have anything to do with my recommendation today.

Instead, three separate computer-based buy signals are flashing bullish signals on the real estate sector, and I have a possible triple-digit opportunity for you.

Let me explain.

Three Buy Signals for the Real Estate Sector

Let’s start with the three buy signals on the sector before I give you the opportunity.

The first is the most basic, a price chart of the SPDR Real Estate Select Sector ETF (NYSE: XLRE).

This is showing a possible breakout of a long trend channel.

It may have just had a false breakout, since the price jumped above the trendline, then fell back below it. But this can also hold as a new, steeper uptrend for the exchange-traded fund (ETF). As long as it can hold above its previous peak, around $33.50, prices should continue to climb.

The second is a seasonality chart.

Right now, it is a great time to enter the real estate sector based on a 10-year seasonal analysis of the Vanguard REIT ETF (NYSE: VNQ). I used this ETF because it has data going farther back that the newly listed XLRE in the price chart.

December is clearly the strongest month to be in real estate, and we bought a real estate investment trust (REIT), a couple of weeks ago that is already benefiting from this trend.
