Gold has been surging in recent months after the Federal Reserve said it could raise interest rates in March.

Gold futures have gained nearly 7% since last October.

On Tuesday, the S&P 500 gained 1.5%, while the Nasdaq composite index rose 3.9%.

But some experts question whether the Fed should hike rates, given the uncertainty surrounding the global economy and the potential for a global financial crisis.

If the central bank does raise rates, it would mean higher rates for Americans, said John Van Praag, an economist at the University of Massachusetts, Amherst.

But if the Fed raises rates in a way that reduces inflation or helps spur the economy, it is likely to do so to help the economy as well as the Federal reserve, Van Praak said.

“It is going to do that by reducing inflation and helping to stimulate the economy,” Van Praags said.

A buyback is a government policy to buy up a portion of a company’s assets to boost the value of its stock.

The buyback can be used to buy back shares of the company, which are sold for a fixed price.

The buyer of a share can sell the shares and receive a payment of up to the purchase price minus a percentage of the value that the shares were valued at at the time of purchase.

The federal government pays for the buyback, known as the “taper tantrum,” by increasing the tax on financial assets.

But experts question how much the government should be paying to support the market and the broader economy.

The Fed has said it will raise interest rate targets in March, which will likely be used as a signal for investors to consider buying shares in the stock market.

But Van Praaga said he doubts that the Fed will raise rates until March.

“That will be a long time, maybe two years, before they have any effect on the economy at all,” he said.

But the market is moving ahead, he said, adding that the S-curve is now “in the green.”

“If you look at the long-term trends, the Fed’s actions should be viewed as a continuation of the market’s recent performance,” Van Raag said. 

In other news from Tuesday, The Wall Street thesaurus added a definition of “substantial” to the definition of “significant” to include an amount of money that is significant, while also not being “massive.”

The dictionary also added a link to a new version of its substantial  definition. 

The definition has substantially changed since the original version, which was published in 2017, said a Wall Street Dictionary editor.

The updated definition now includes significant, subsequent and recently, he added. 

A link to the new definition has also been added to WallStreetThesaurus.
