Create redirect with parameter in Laravel routes

I have this route in my web.php:

Route::get('/fr/action/{ticker}', 'AnalysisController@index')->name('analysis.slug.French');

I want to create a 301 redirect from this page to '/stock/{ticker}' but I'm not sure how to pass the $ticker parameter to the redirect here.

This doesn't work:

Route::get('/fr/action/{ticker}', function() { return redirect()->to('stock/{ticker}') });

I am not sure but this might work;

Route::get('/fr/action/{ticker}', function($ticker) {
    return redirect()->to('stock/'.$ticker);
});

But better solution from official docs, you can create a route and redirect named route with parameter.

EDIT:

Route::get('/fr/action/{ticker}', function($ticker) {
    return redirect()->route('yourDefinedStockRoute', ['ticker' => $ticker]);
});

yourDefinedStockRoute is the name of "stock/{ticker}" route
