There are three funds hiding in plain sight that do something everyone thinks is impossible: pay huge dividends with yields up to 7.2% — and deliver outsized total returns of more than 24%, too.

I know I don’t have to tell you what an inflation-fighting weapon a return like that would be these days.

These are no less than the world’s three best-performing closed-end funds (CEFs) over the long term, and today we’re going to rank them from third to first to see if any (or all!) of them have a place in our investment portfolios.

“World’s Best” CEF No. 3: 24% Annual Returns for Years and Years

The least impressive CEF on the list, the Columbia Seligman Premium Technology Growth Fund (NYSE: STK), has “only” a 23.7% annualized return, based on its market price, over the last five years, with a dividend that’s held steady throughout that time (and yields 5.1% today). Meantime, STK’s underlying portfolio, or net asset value (NAV), has ballooned.

(CEF investors will know that when measuring these funds’ performance, we need to look at two numbers — the NAV return and that posted by the fund’s market price, which is the return we get. Due to a quirk in CEFs’ design, these figures can be very different.)

Third-Place Fund Beats the Market

The stellar performance of STK’s holdings is due to the fact that they’re a mix of smaller tech companies, like Lam Research Corp. (Nasdaq: LRCX), Teradyne Inc. (Nasdaq: TER) and Synpatics Inc. (Nasdaq: SYNA), combined with big, cash-rich tech stalwarts like Apple Inc. (Nasdaq: AAPL), Alphabet Inc. (Nasdaq: GOOGL) and Microsoft (Nasdaq: MSFT).

Thanks to this portfolio, investors who put $100,000 in STK in late 2016 are now sitting on $216,300 in profits, nearly double what the S&P 500 has delivered. And its dividend is four times greater than the S&P 500 average, too.

“World’s Best” CEF No. 2: A 28% Yearly Return and a 7.2% Return in One Buy

STK has held a consistent dividend over the long haul, while the Liberty All-Star Growth Fund (NYSE: ASG) has increased payouts over the last decade, which is why it now yields an impressive 7.2%. And that huge payout is sustainable — the fund’s high-octane portfolio has backed it up with an incredible five-year run, posting a total NAV return of 198.3% in that time:

Another Market Beater

Meantime, ASG’s market price has outrun its NAV, with a 247.1% return. In other words, ASG investors who bought in five years ago have now banked a $247,100 profit for every $100,000 invested.

Similar to STK, ASG focuses on companies that are seeing soaring revenue. But unlike STK, ASG doesn’t stick just to tech, instead aiming for growth stocks across sectors.

That’s why ASG holds stocks as different as Signature Bank (Nasdaq: SBNY), education services firm Chegg Inc. (NYSE: CHGG) and insurer UnitedHealth Group Inc. (NYSE: UNH). The result has been a massive market-beating return and a high income stream that keeps on rising.

“World’s Best” CEF No. 1: A 5.5% Dividend and Unbelievable 31% Yearly Returns

The CEF with the all-time best market performance (going by its market price) is also our most appealing buy of this trio today: the BlackRock Science and Technology Trust (NYSE: BST).

BST Nearly Triples Up the Market

With a 31% annualized return over the last five years, this relatively new (launched in 2014) fund has stayed under the radar for many investors. For those in the know, however, a $100,000 investment has returned $302,400 in profits in the last half-decade, with BST’s payouts steadily increasing in the last few years, along with its ballooning portfolio.

Income Goes Higher and Higher

All of this makes for a great CEF, and that’s why BST should be on the top of your “buy now” list. But there’s another reason this fund is a great deal: Unlike ASG and STK, which trade for premiums to NAV — CEF-speak for saying these funds trade above what their portfolios are actually worth — BST trades for less than its portfolio’s real value.

Right now, BST’s market price is 4.7% below NAV, meaning you get its holdings, which include Inc. (Nasdaq: AMZN), PayPal Holdings Inc. (Nasdaq: PYPL) and Alphabet Inc. (Nasdaq: GOOGL), as well as a few private-equity firms BlackRock has access to (but your average investor doesn’t) for less than these companies’ real market value.

For that reason, BST is our No. 1 pick of these three now — especially since it will also give you a 5.5% income stream that’s likely to keep rising while you hold it.
