Thanks, Chris. EARN had a very good quarter with total return of 5.1%, bringing our economic return over 8% for the year. I view this as a very good outcome, given the extreme volatility we had earlier in the year. Our core earnings has easily covered our dividend this year. And as of last night's closing price of $11.13, our stock has had a total return over 13.5% this year.
We've also kept our debt-to-equity ratio low, below 7. So we have lots of room to add additional mortgage exposure. Armed with ample cash and low leverage on our balance sheet, we should be well positioned to play offense if there is any year-end volatility.
While the themes that we outlined for the second quarter largely played out again in the third quarter, the macroeconomic backdrop for a levered Agency MBS strategy still remains strong today. Most significant is the consistent, large and predictable Agency MBS purchases for the next few quarters that the Fed is telegraphing. The Fed is buying a lot, it's buying every day, and it's telling the market it will continue to buy a lot.
In addition to the Fed, other pools of capital, such as banks are, also big buyers of Agency MBS. This is significant because while the Fed is buying a lot, supply is absolutely enormous, whether you look at it on a gross or a net basis as you need significant buyers to absorb it all.
Gross supply, which is simply the volume of new Agency mortgages originated, is expected to be an unprecedented $3 trillion plus this year. To put this number in context, the gross supply in 2019 was approximately $1.5 trillion. Net supply, which subtracts paydowns from the gross supply number is expected to be over $400 billion this year. This net supply number is the amount of new capital that has to get invested in the Agency MBS market for the supply to clear the market, and that net supply number is also enormous on a historical basis. And in addition to the net supply from origination, the MBS market will also have to be able to absorb the volume of secondary market sales, such as Freddie Mac, who has been mandated to shrink their portfolio.
The Fed does a lot of heavy lifting to absorb all the supply, but they can't do all of it. Remember that they came into this round of QE with a giant portfolio that's paying off very fast, recently between 30 and 35 CPR, and the Fed has to reinvest those pay downs just to maintain a constant portfolio. As it turns out, even with this large volume of purchases, the Fed's net buying in recent months has only been roughly equivalent to the net supply. So to have an orderly market, you'll still need to have a steady source of buyers to absorb the supply from the secondary market. The good news is that given all the concerns about credit risk post COVID, the MBS market has plenty of other buyers. Relative to Treasury, the extra yield on MBS without credit risk is currently attracting a wide range of investors. And given that MBS financing is widely available in huge size and it's almost free, we think that MBS make the most sense in the levered form, which is exactly what a mortgage REIT does.
Another tailwind now is that the drag on net interest margin to insulate a portfolio from interest rate risk is close to 0, and in some cases, is less than 0. You actually can get paid to be short, which is a relatively modest drag on our NIM. We can run a fully duration hedge portfolio, which by itself helps to stabilize book value.
Even with their strong Q3 performance, several TBA coupons that we've been long still look attractively priced to us with or without attractive rolls. When you add this to the value of special rolls, the levered returns are fantastic. Rolls are benefiting from the perfect storm of front month fed buying and back month mortgage banker selling.
But we also see headwinds, too, that argue for -- against being fully levered. Specifically, prepayments are blazing, and mortgage companies are aggressively staffing up. We don't see any compelling reasons for a slowdown of the refi wave outside the normal seasonal effects. We believe that some of the COVID-related workarounds that the GSEs put in place in the spring, such as exterior appraisals and the use of e-notaries, are here to stay and that these innovations only make speeds faster. Of course, we are always working to mitigate many of these risks to our portfolio construction. I'm happy that we were able to keep our CPR down in the portfolio to a very manageable 21.4%.
Another risk we think about is sustainability of roll levels. Rolls are great while they last, but you can't count on them in perpetuity. The only large TBA coupon that underperformed Treasury this month was 30-year 3s TBA. After the Fed stops buying them, the roll collapses. And once the roll collapsed, the price collapsed.
Reviewing how we were positioned for the quarter and what worked. We were long TBAs with big positive rolls, which was great, but we also benefited from being short TBAs with negative rolls. So we won both ways. It sounds simple, but it worked well this quarter. Being short negative rolls is the way you get some of your hedging costs down below 0.
In addition, as I mentioned, our realized prepayment speeds were well contained. The size of our Agency portfolio was roughly constant quarter-over-quarter. We like mortgage valuations coming into the quarter, but mortgages have done well, so they are not as cheap as they once were. We still really like some of the shorter maturity MBS, like 15-year mortgages. The Fed buys them, the rolls are good, and they don't have anywhere near the same extension risk as 30 years, which makes the hedging simpler.
Also, during the third quarter, as Larry mentioned, we sold many of our non-agencies which we -- that we opportunistically bought last quarter. Prices in that sector have gone up a lot since the market melted down, yields are back down to less interesting levels, and the credit risk may be priced wider depending on the future path of stimulus and economic recovery. So we opted to monetize a good chunk of that portfolio.
Heading into the last 2 months of the year, a big focus of ours will be avoiding prepayment mistakes, but without paying so much for prepayment protection that our assets will be out of favor and a big market sell off. We'll not only want to stay thoughtful about what the Fed is doing right now, but we'll also want to anticipate what the Fed is going to do in the future. The worst-performing coupon for the quarter by a wide margin was TBA Fannie 3s. As I mentioned earlier, that's because Fannie 3s went from being the coupon that the Fed is buying to a coupon that the Fed was buying. The roll collapsed, and the price collapsed. And given that we're in the middle of a refi wave, the current market environment presents lots of great opportunities to put our prepayment knowledge to the test. So I'm very optimistic about the return potential.
Now back to Larry.
