The firm enjoys very stable demand for its products, and consequently it has a low equity beta of $0\mathrm{.}525$ and can borrow at $3\mathrm{.}7\%,$ just $20$ basis points over the risk$-$free rate of $3\mathrm{.}5\%.$ The expected return of the market is $9\mathrm{.}8\%,$ and PKGR$\text{'}$s tax rate is $28\%.$

a$.$ PKGR believes it can increase debt without any serious risk of distress or other costs. With a higher debt$-$equity ratio of $0\mathrm{.}525,$ it believes its borrowing costs will rise only slightly to $4\mathrm{.}0\%.$ If PKGR announces that it will raise its debt$-$equity ratio to $0\mathrm{.}525$ through a leveraged recap, determine the increase or decrease in the stock price that would result from the anticipated tax savings.
